• Key questions:
• What is the BoK?
• How to operationalize it?
• What can it be used for?
• How can it evolve?

Each concept will be tagged with a version
number*. The current version will be designated
with a “b” tag (i.e. V1.5b). This tag will be given to
all concepts that are yet to be approved.
Applications can access any version through the
use of the versioning tag field.

Authoritative Product
• A "top down" approach in which experts in those disciplines review
additions/changes to the GIS&T BokOnto to determine what concepts are
accepted in the next version (traditional editor).
• Scores for confidence in a new concept and its connections could be
generated from the bottom up in a collaborative fashion through assertion
and debate by the community (Ahearn et al., 2013) .
• Scores for new concepts could be inferred through data mining of the
contributors publications to generate a weight for each concept they wish
to add/modify. The concepts parent would be used for the scoring metric.
• Scores could for new concepts could be determined through the
nature (confirmation of existing content, correction, or revision) of a
contribution (Keßler and de Groot, 2013).
